“…Despite using lower acid concentration and shorter duration, the hemicellulose reduction was more significant in the A10–1.5 pre-treatment (1.5% of acid concentration for 10 min) compared to the pre-treatment with higher acid concertation and longer duration A15-2 (2% of acid concentration for 15 min). These results highlight lower acid concertation's selective degradations and preservation effects for a shorter time [ 34 ]. The shorter reaction time may limit the extent of cellulose degradation, contributing to a higher cellulose fraction despite the reduction in hemicellulose content.…”

“…1. Distribución de sacáridos obtenidos en la hidrólisis ácida del rastrojo de piña El pretratamiento con ácido sulfúrico diluido del material lignocelulósico permite tener mejoras en el rendimiento de producción de glucosa, puesto a que este incrementa el área superficial y el volumen del poro, altera la estructura lignocelulósica al degradar la lignina, solubilizar la hemicelulosa y fragmentar la estructura cristalina de la celulosa [36]. La concentración de glucosa obtenida en la corrida 6 de 1.72 g glu /100 mL dis (10.29 g glu /100 g MS ) presentó valores superiores a los analizados en estudios realizados con otras materias primas bajo condiciones similares de hidrólisis, como lo son: el aserrín, 3.15 g glu /100 g MS [37] , la caña de azúcar, 1.46 g glu /100 mL dis [25], bagazo de arroz, 3.3 g glu /100 g MS [38], pasto, 2.83 g glu /100 g MS [39], moringa, 8.40 g glu /100 g MS [40].…”

“…Several different acids used in pretreatments of SCB, including dilute sulfuric acid [29][30][31][32][33][34][35], dilute hydrochloric acid [36], dilute phosphoric acid [32,37], and dilute nitric acid [38], have been reported. High hydrolysis yields have been obtained when lignocellulosic biomass was pretreated with dilute sulfuric acid compared with hydrochloric, phosphoric, and nitric acid [22].…”
